Our take

Written Aug 3, 2026

MiMo-V2.5-Pro is a trillion-parameter text model from Xiaomi with a permissive MIT licence and a one-million-token request limit. It is built for long-document and coding workloads, with measured coding performance well ahead of its general chat score.

Who should pick it

Choose this for coding workloads where its measured coding score is the relevant signal, or for long-context text tasks at low entry cost with a genuinely permissive licence. Use it when you want to self-host or modify weights commercially. Skip it if you need image, video or audio support, if creative writing quality matters most, or if you want the cheapest throughput rather than the fastest.

The case for it

  • One of the longest request limits among open models we track, at 1,050,000 tokens, with low entry cost.
  • Measured coding performance sits 52.6 points above its general chat score — its strongest single benchmark.
  • MIT licence permits commercial use, modification and redistribution without restriction.
  • Ten hosted offers with a wide throughput range, from 20 to 65 tokens per second.

The case against it

  • Creative writing is its weakest measured task, 87.2 points below coding and 34.6 points below general chat.
  • Fastest throughput costs nearly three times the output price of the cheapest option, and over four times Xiaomi's own mid-tier offer.
  • Text-only: no image, video or audio input or output.

Arena Agent (IPS) is the only board that has scored it for this.

WritingWe do not rate this

Scored, not ratedThe placings are on the right.

Two boards come close and neither tests writing: Arena Creative Writing asks people which of two replies they prefer, and LiveBench Language tests whether a model understood a passage. So we show where MiMo-V2.5-Pro placed and give it no mark out of five.

Arena Instruction Following 14th of 143

These tests check whether a model follows instructions — a precondition for all the work above, but not a measure of how well that work is done, which is why they get no rating.

What each host's API supports

From the parameter list each endpoint publishes. Streaming is omitted: nothing we hold reports it, for any model.

What we do not know about this model yet

  • We hold no measured file for it, so all 3 sizes on this page are calculated from the parameter count.
  • 2 of 10 listings publish no parameter list, so what their API accepts is unknown to us.
  • Nothing we hold says whether an endpoint streams, so we do not show it either way.
  • 3 of 10 listings do not say whether they train on prompts.
